Vortex Viper Gen I (VTX A) Throw Lever

Upgrade your Vortex  optic with our Vortex Viper Gen I (VTX A) Throw Lever, speeding up magnification changes and target engagements without breaking the bank. Throw levers are especially useful in a number of different scenarios including but not limited to precision shooting competitions and cold weather hunting.  Our standard polymer Throw Levers are printed using one of our industrial oriented 3D printers. . Our levers are proudly printed in the USA from a custom made durable Nylon 6 material, and feature a metal thread insert for increased strength when tightening. Easily installs in a minute or less. Nylon 6 does not have the tensile strength of aluminum, but is extremely durable and will flex and yield under hard impact rather than damaging or marking your optic. This feature can be useful in a number of situations including shooting competitions and hunting when a throw lever may snag. Our levers feature a lifetime warranty.


The VTX A model fits Vipers with a hard magnification ring that has longitudinal grooves.  Vipers with a stippled rubber magnification ring need the “VTX R” model which can be found here, and a Gen II Viper lever can be found here.


Available in the following materials:

Black Nylon

Carbon Fiber Nylon

More Information About FDM Printing.

Fused deposition modeling (FDM), or called filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer.

    I’ve had other throw levers…

    But NONE of them have been anywhere near the strength and quality of those offered by MK Machining.
    They are now my Only throw Lever supplier. Period.

  3. Jerry Barber (verified owner)

    Excellent quality and customer service. Solid quality product. I have four rifles and there is an MK lever on every one. I highly recommend them to anyone that owns a rifle.
